SHEET-GLASS-CUTTER HOLDER.

Application filed September 21, 1916.

To all whom it may concern:

Be it known that I, GEORGE W. KLAcEs, a citizen of the United States,residing at Pittsburgh, in the county of Allegheny and StateofPennsylvania, have invented a new and useful Improvement in Sheet-GlassCutter Holders, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpartof this specification, in which Figure 1 is a side elevation of oneform of diamond holder built in accordance with my invention, showingthe gage in position for cutting the diamond point.

Fig.2 is a plan view with parts in section, as indicated on the lineIIII of Fig. 1.

Fig. 3 is a perspective view of the angle piece for connecting thecarrier for the diamond holder to the holding bar.

Fig. 4 is an end view of the carrier, showing the diamond holder inposition.

Fig. 5 is an end view of the collar for supporting theangle piece shownin Fig. 3; and

Fig. 6 is a perspective view of the gage. Thls lnventlon relates to animprovement in tool holders, and is more particularly designed forholding diamond points for sheet glass cutting machines.

The object of my invention is to provide a cheap and eficient device ofthis character which is so arranged that the diamond point can first beset y means of a gage to its proper position and lined up to make thecut, and then secured in its adjusted position. After the diamond hasbeen set to its position with relation to the gage, the holder thereforcan then be adjusted in two directions, one of which is approximately,at right angles to the other, about an axis which is approximatelycoincident with the cutting point of the diamond.

By this arrangement I and enabled to first set the cutting point bymeans of a gage and line up the face of the diamond in the direction ofits travel; and at the same time provide means for universally adjustingthe diamond holder about axes which are coincident with the point of thediamond without shifting the position of said point.

The precise nature of my invention will be best understood by referenceto the accompanying drawings, it being premised, however, that variouschanges may be made Specification of Letters Patent.

in the details of construction and arrange ment of the various parts,without depart- 1ng from the spirit and scope of my invention as definedin the appended claims.

Referring to the drawings, the reference character 2 designates theholding bar which may he graduated in any desired manner, and which isof the proper shape for attaching it to the machine on which it is to beused. Connected to one end of this bar is a collar 4, which is fixedlysecured thereto by means of a through pin 5, although it will readily beunderstood by those familiar with the art that the collar may be securedin various other ways. This collar 4 is provided with an arc-shapedprojection 6. 7 is an angle member having an arc-shaped slot 8 for thereception of the rounded end of the bar 2, and is also provided with anarc-shaped slot 9 for the reception of the arc-shaped projection 6 onthe collar 4. 10 is a nut on the threaded end of the bar 2 for securingthe angle piece 7 in position thereon, and interposed between the nut 10and the angle piece is a washer 11. The other arm of the angle piece 7is provided with an arc-shaped slot 12, similar to the slot 8, as wellas an arc-shaped slot 13, which is similar to the arc-shaped slot 9, andwhich are adapted for securing the carrier 14 in position on the anglepiece.

This carrier 14 is provided with a through opening 15 which is arrangedto receive a circular diamond holder 16, and which is secured inposition by means of a screw 17. The upper end of this diamond holder isprovided with a lmurled head 18, while the lower end is provided with asuitable cavity in which is secured the diamond 19.

The carrier 14 is provided with a screw stem 20 which is arranged topass through the slot 12, and 21 is a nut for securing the carrier inposition on the angle piece 7. 22 is a washer interposed between theangle piece and the nut 21. The carrier 14 is also provided with anarc-shaped projection 23 which is seated in the arc-shaped slot 13,which projection is similar to the projection 6 on the collar 4. Theangle member 7 and the carrier 14, with their connections, form auniversal adjustable support for the diamond holder which will permitthe adjustment of the holder in two planes at right angles to each otherabout the point of the diamond 19, to change the angle of the diamond.

- 2a is a gage for setting the diamond point, nd which is provided witha recess 25 adapted to receive the squared portion of the bar 2. Thisgage is also provided with a downwardly and forwardly extending arm 26,which is provided with a diamond setting surface 27 When it is desiredto set the diamond holder in the device, the gage is applied to the baras shown in Figs. 1 and 2. The diamond holder 16 is then passed throughthe carrier and the point of the diamond is brought into contact withthe surface 27 of the gage. The holder 16 is then rotated to place thediamond in proper cutting position, after which the screw 17 istightened to secure the holder in position in the carrier. The gage 26can then be removed, and the nuts 10- and 21 are tightened to rigidlysecure the various parts to each other. The device may then be tried,and if it does not make the proper out, the carrier let may be adjustedon the angle piece 7 while the angle piece 7 may be adjusted on thecollar 4 on the projections 28 and'6. Both of these adjustments beingapproximately on arcs struck from a center which is approximatelycoincident with the point of the diamond, the arrangement being suchthat the holder 16 may be adjusted in directions at right angles to eachother without approximately changing the position of the point of thediamond.

It will readily be understood by those familiar with the art that othercutting tools than diamondsmay be secured in a holder of this character.

The advantages of my invention result from the provision of a toolholder having supporting devices which are arranged to be adjusted inone or more directions about the cutting or working point of the toolwithout changing the position of the point thereof.

I claim 1. A device of the character described comprising a diamondholder, a carrier therefor, said diamond holder being arranged to beadjusted within thecarrier, a support for the carrier, said supporthaving a guide for the carrier arranged to permit the carrier and holderto be adjusted about the point carrier in its adjusted position to thesupport, a holding bar, supporting connections between the holding barand the support arranged to permit the support to be adjusted about thepoint of the diamond at right angles to the adjustment of the carrier onthe Oopiesof this patent may be obtained for five of the diamond, meansto secure thesupport, and means for securing the support in its adjustedposition, substantially as described.

2. A device of the character described, comprising supporting means, aholder for a diamond adjustably secured in the sup porting means, aholding bar for the supporting means, and a universal connection betweenthe holding bar and the supporting means arranged to permit the diamondholder to be adjusted in two directions at right angles to each otherabout the diamond point as a center, substantially as described.

3. A device of the character described, comprising supporting means, aholder for a diamond adjustably secured in the supporting means, aholding bar for the supporting means, and a universal connection betweenthe holding bar and the supporting means arranged to permit the diamondholder to be adjusted in two directions at right angles to each otherabout the diamond point as a center, said holding bar being arranged tofixedly support a gage for setting the point of the diamond,substantially as described.
